Wasn't fully satisfied with how the other single piece "Ultimate" bushings performed;
The 2 piece design solves every issue with door bushings, so they're longer lasting and have a tighter, more solid fit.
They have the same adjustability as the single piece design, and are WAY less prone to cracking thanks to the extra damping and the soft, grippy base layer (requires less bolt torque to keep them in place). Use as big of a washer as you can fit
The soft bumper does not decrease chassis rigidity!
All of the rigidity that door bushings supposedly add (it's all placebo, they just get rid of some rattles) comes from the sides of the bushing coming in solid contact with the door cup: this is another area where the 2 piece design improves over the generic solid shells, as it effectively adds preload to the system

No supports required; parts already oriented for best results
- Rigid part @ 0,2mm layer height: at least 4 horizontal perimeters, at least 11 bottom solid layers, 40% infill
ABS recommended. PLA is probably good as it's very rigid and these part shouldn't be seeing extreme temperatures,
- Soft part @ 0,2mm layer height: at least 5 bottom solid layers, change horizontal perimeters and infill depending on the desired hardness (I did 4 perimeters and 40% infill)
PP or TPU recommended (or any other flex / semiflex material)

“DoorBushing-Soft" and "DoorBushing-Rigid”: the 2 parts are meant to be printed individually, and have been exported with the proper tolerances and compensations.
“2 Piece – MMU”: the 2 parts are meant to be printed in the same print with a multi material / AMS unit. There are no tolerances.

Please do NOT sell these files. I see you trying to sell my designs in the 3d printed Miata parts fb group ( grossly overpriced as well). have some dignity. Design your own
